MINOR: trace: support all source alias on -dt

Browse Source 
Command line argument -dt can be used to activate traces during startup.
Via its optional argument, it is possible to change settings for a
particular trace source. It is also possible to update every registered
sources by specifying an empty name.

Support the trace source alias "all". This is an alternative to the
empty name to update every sources.
